Need help with the first three questions, and please explain step by step how to do it the easiest way possible.
The students in a class get to decide on the color of the classroom. The two choices are blue and yellow. Polling shows yellow is preferred by a small

some yellow supporters who would actually vote for red. The results of the vote are below.
Blue
Yellow
Red

d
Red did not win the vote, but it draws enough support away from yellow to make blue the winner, even though a majority of
students preferred yellow over blue when there were two choices.
Red did not win the vote, but it had no effect on drawing enough support away from yellow to make blue the winner, even though
a majority of students preferred yellow over blue when there were two choices.
Red did not win the vote, so because of this, yellow should win the vote over blue.…
